Circuit breakers within the household provide one main purpose. It is a fail safe in case a fault with electrics occurs and causes an accident.
If a person is exposed to bear electrical wiring then without circuit breakers, this could result in severe burns or even death. Many homes come as standard with such facilities and is a legal requirement worldwide before putting a home up for sale on the open market.
Never risk the lives of you or family members by skipping such important safety issues that can mean the difference between life and death just to save a few dollars.
